IMPROVEMENT IN RAILWAY-CAR COUPLINGS.

Specification forming part of Letters Patent No. 120,610, dated November 7, 1871 antedated October 21, 1871.

To all whom t may concern:

Be it known that I, ANsoN A. ATwATER, of Trumansburg, in the county of Tompkins and State of New York, have invented a new and valuable Improvement in Coupling or Uniting Railway Gars called a Gar-Coupling; and I do hereby declare that the folles-"ing is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of v a top view of my invention. Fig. 2 is a central vertical longitudinal section, showing the pin set to receive the link. Fig. 3 is a similar sectional view, showing the pin in the link.

This invention relates to improvements in carcouplins; and it consists in producing a device I'or that purpose, hereinafter fully described, the object being to provide an automatic machine for the coupling 0I' cars. The rectangular casing A has at each side of its upper and lower walls a a slide-guides b b', between which moves the bar or slide c. slotted, and provided with ears at d for the admission of the end of the elbowed lever e and the support of its fulcrum. The casing A is perforated on its upper and lower sides a a', as shown at h, for the admission of the pin g. It is open at the end k for the admission of the tongue or link i, and suitably connected to the car. The link 'i is connected to another car, and slotted or perforated for the passage of the pin g. The elbowed lever e has at its lower end, which is The under side of the casing A is,

free, a bulb or weight. Its upper end is inserted into a recess in the slide c, and it works loosely therein when the slide moves back and forth. It

is supported at its angle by a pivot resting in` the ears d.. The elbowed lever e is pivoted at its angle to a support projecting upward from the casing A. Its upper end is provided with a bulb or weight, and its lower end is pivoted to the end of a link, f, to the other end of which is pivoted the coupling-pin g, the link f serving to permit the pin g to retain a vertical position when the lever e is moved. The parts being in the position shown in Fig. 2, the machine is ready for automatic operation, when the link i is pressed against the end of the slide c, the slide e is forced back, the pin g :is released, the slide o moving.

om under it, and the weight Zraised. At the same time the tongue 'i enters the casing sui-liciently to bring its opening under the pin g, which, in consequence of its weight and the weight ofthe bulb l', drops through the opening in the tongue 'L' and the perforation h, and the cars are coupled, as shown in Fig. 3.

I claim as my invention- 1 The combination with the slide c, engaging with the weighted elbow-lever c, of the pin g, link f, and weighted elbow-lever e', substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of WILLIS G. ATWATER. (122)
